ROTARY PLOWI-NG-GYLINDER.

To all whom it may concern:

Be it known that I, CHASE G. REED, a citizen of the United States, residing at Toledo,

reference to the construction of the cutting element itself. The obj ect of my invention is the construction-of a simple, strong and efieetive cutter, particularly well designed and adapted to accomplish the work for which it is to be used, and having the novel and useful construction and arrangement "of parts which is pointed-out in the appended claims. I

In the accompanying drawings Figure 1 is a side view of a plowing machine in which my invention is embodied; Fig. 2 isan end view, partly in section, of the plow or cutter; Fig. 3 is a plan view of a portion of the same; Fig. 4 is an end viewof' a modified form of cutter"; Fig. 5 is a side view of one nd of such modified form; Fig. 6 is a fragmentary view on a larger scale than Fig. 2 and showing a modified form of attachment of the cutting blade to the back plate of thecutter; and Fig. 7 is'afragmentary side view showinga staggered relation of the supporting plates between thev blades.

The same letters of reference indicate the same parts in all of the figures of the'drawin s.

' y way of illustration merely, and in order toshow the manner in which a cutter constructed according to my invention is designed to be used, I have in Fig; 1 illustrated a plowing machine of which my novel cutter forms a part. It is unnecessary here toeirplain the construction of the ma chine further than to say that it includes a wheeled main frame 1, a plow frame 3 flexibly connected to the main frame carrying a bathing shield 4 and supporting the cutter which will shortly be described in detail, a hoisting and counterbalancing mechanism 5 connected to the plow frame, and a .gasolene engine 6 mounted on the main frame and arranged to rotate the cutter rapidly and also arranged to drive the traction Specification of Letters Patent.

' Application filed November 15', 1916, Serial No. 131,544. Renewed January 8, 1919. Serial No. 270,214.

gage wheels 10 are provided to'governthe depth of cut of the plow.

(lomlng now to the novel cutter structure which constitutes "my present invention, the

shaft 7 of the cutter through spider frames 11 supports a cylindrical shell 12 which carries a series of longitudinally arranged back i plates '13 equipped with cutter blades 14, which are secured to it in any desired or suitable manner, eitherlremovably, as by means of screws or bolts, or irremovably, bywelding by rivets, which must be destroyed in order' to? remove the blade.

While it is obvious that the cutter blades might be formed in tegral with the back plates 13, yet it is desirable to construct the parts as above described, in order that a broken or defective 1 blade may be removed and replaced-without "disturbing other parts of the plow structure, and with the construction shown this may readily be done, even'though the blade be riveted to the back plate. In the form shown in Fig. 2, the back plates 13 extend the entire length ofthe shell; Preferably the blades 14 are shouldered near their edges I in order to form a. seat to accommodate the forward edges of such back plates upon which they are seated in the manner shown inFig. 2. The back plates are secured to the shell 12 by means of-spacing plates 15,

' which in the form of my invention shown in said Fig. 2 are arranged inringg of such plates in alinement' with each-other. .shownin the figure referredto, each plate 7 is formed with a curved-flange 16 at its base, by means of which it is riveted to-theshell,.and a front flange 17 and rear flange 18 which are respectively riveted to the back plate 13 which lies in frontof it the back plate lying to the rear. Preferably, to give maximum-strength, the'back plates to receive such flange 22, see Fig.2 and the right hand plate in 6; The outerend '13 are formed with flanges 22 riveted to the shell 12,the-ba'se-flanges 16 and front flange 17 of the spacingplate 15 being cut away of the} flange 17 'abuts against the rear of the blade 14;, whilethe front outer corner of the plate 15 fits against the rear of such blade, thus giving the blade support and holding it in position. Since the spacing plates 15 are arranged in alinement with each other extending in rings entirely around the cylinder or shell 12, they brace each other in the same manner as a solid or integral-ring would, and in effect form con tinuous solid rings intersecting the back plates and cutter blades and dividing the space between them into a series of buckets.

In Fig. 6 I have shown at the left hand side, a form of construction in which the back plate 21 abuts directly against the shell 12, and the front flange 24: of the spacing plate '25 alSO abuts the shell, the base flange of the spacing plate being continued to a point where it abuts against the front flange. As also illustrated in Fig. 6, the blade 14 may be so formed as to fit the forward side of the back plate, the plate being in such case preferably offset as shown so as to present a smooth forward surface.

In Figs. 4: and 5 I have illustrated a form of cutter in which the back plates 19 and .blades 20 are relatively short, and several series of such plates are arranged in bands along the shell .of the plow, the members of one series alternating with those of the others in staggered relation.

In Fig. 7 I have illustrated a modified form of my invention in which back plates 31 equipped with blades ll extend the full length of the plow, but in which the spacing plates 15 are arranged in offset or stepped relation, instead of in alinement to make up rings of plates. The spacing plate may also be arranged in spiral form, if desired, and it is obvious that still other modifications and variations in the arrangement of parts may be made without departing from the spirit of my invention.

l Vhile in the drawings and foregoing specification I have illustrated and described my novel form of plow as arranged to rotate in such direction that the cutters will move forwardly in entering the earth, and the soil will be carried upwardly around the plow, it will be understood that it is also well adapted for use in a plowing machine in which the cutter is arranged to rotate in the opposite direction and throw the earth directly to the rear.
